Measurement Category
To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various
electrical environments, categorized as O to CAT.IV, and called measurement categories. Higher-numbered
categories correspond to electrical environments with greater momentary energy, so a measuring instrument
designed for CAT.III environments can endure greater momentary energy than one designed for CAT.II.
O : Circuits which are not directly connected to the mains power supply.
CAT.II : Electrical circuits of equipment connected to an AC electrical outlet by a power cord.
CAT.III : Primary electrical circuits of the equipment connected directly to the distribution panel,
and feeders from the distribution panel to outlets.
CAT.IV : The circuit from the service drop to the service entrance, and to the power meter and
primary overcurrent protection device (distribution panel).
